Pro tip?



No offense intended. I suppose if all you are doing is dropping the oil and spinning a filter in, it'll do.
I view "oil change time" to be so much more than just an oil exchange. Yeah, it takes me over an hour, but this is the time to rotate tires, check brakes, check for leaks, lube grease zerks on vehicles that have them, shake rattle and roll the suspension components to make sure things are tight, check diff/transfer levels, check tire wear, and give an eye to all those things that are under the vehicle.
Heck, I even view this as a good time to clean and seal the barrels of the wheels while rotating tires and clean things on the underbody. Simply can't be done standing over the engine bay.
I'm not knocking this extraction method, but if I'm worried about the mess (I don't make) or getting a little dirty... well... I'm just not. There is no mess with one of the valves discussed above. You can drop the oil and never spill a drop. Yeah, you have to empty the pan back in to the oil containers, but you're doing that either way.
I have a pneumatic extraction tank, I've used it a couple of times on vehicles, I used it a lot when helping my Dad with his small engine business. He's gone now, but the truth is it just sits. I just look at this oil change method as the only or a regular means as, opportunity lost.
